Since the game is meant to be web-based, resources will be lazy-loaded, where possible. Right now this is made as soon as the cards are instanced (with a silly placeholder) but in the future the images probably will be fetched before the match even starts. This does pose an issue for competitive matches (you can sniff the traffic and know the opponent's deck) so I'm not yet totally sold on that idea.
Your generic mastodon instance for people who just want to have fun. Rules are pretty simple and moderation is lax, just remember to be a good boi!
